Patented Aug. 25, 1931 UNITEDSTATES PATENT OFFICE KENNETH DALE emu-r, or warms, wasnmoronsH'meLE-sHAxE nmommi Application filed February This invention relatesto a machine'for treating or surfacing shingles to produce what isconventionally known as shakeshingles.

5 Shingles of this character differ from the ordinary shingles ofcommerce by the provision of longitudinally disposed corrugations,composed of alternating ridges and grooves in the shingle portions whichare 1 designed to be exposed to the weather.

' The object of the invention is the provision'of a machine which is totransform ordinary shingles into shake-shingles.

ore specific objects and advantages of 15 the invention will appear inthe following description.

he invention consists in the novel con struction, adaptation andcombination of parts hereinafter described and claimed.

In the accompanying drawings,-

Figure 1 is a plan View, partly in horizontal section, of a machineembodying the invention in its form now prcferre n Fig. 2 is a verticaltransverse section taken 25 substantially on line 2-2 of Fig. 1. Fig. 3is a side elevational view of the machine shown in Fig. 1, parts beingbroken away and parts benw shown in vertical longitudinal section. ig. 4is a vertical transverse section on line 44 of Fig. 1. Fig. 5 is aperspective view of an example of shakeshingle produced according to thepresent invention.

For convenience of explanation in the fol lowing specification, ashake-shingle will hereinafter be designated as a shake, to distinguishthe same from the ordinary which will be designated as such shingleconsisting of a body having plane upper and lower surfaces whichconverge from one end, the butt to the other end, or point of theshingle. To "make such a shingle into a shake, the same is grooved as atA in the top, see Fig. 5, to afford a plurality of ridges B extendingabout three-fourths the length of the shingle from its butt C, the otherportion of the shake remaining with a plane upper surface D.

In carrying out the invention,

I provide a ments and sugport for the front 11, 1925. Serial No. 8,415.

machine having a rigid frame of any known or suitable construction,having, preferably, longitudinally disposed rail elewith a part 12extending above the said rails at'approximately the midlength of themachine. I

13 represents a movable table disposed longitudinally of the frame whichmay advantageously be constructed of a thin metal plate with reinforcingsidebars 13 and ro vidcd at its front and rear ends with le elements 14and 15. The lower ends of the front legs 14 are apertured to receive atransversely arranged shaft 16 which is journaled in bearin boxes 17secured to the frame rails 11 an constituting a pivotal end of thetable. ournaled in the rear legs is a shaft 18 having mounted thereoncams 19 which bear upon rollers 20 rigid with the frame.

As shown in Fig. 3, a cam 19 is provided with a substantiallycylindrical body from which extends radially a projection 21, thelengths of the peripheral surfaces 23 and 23 and projection,circumferentially of the cam, being in about the proportion of three toone.

24 represents an arbor journaled in boxes 25 of the frame and is rotatedas b of a power driven belt 26 passing about an arbor pulley 27. Mountedupon said arbor is a gang of saw blades 28 disposed in inclineddirections with respect to the arbor axis so as to produce erratic orwabbling movements when the saws are rotated with the arbor; the saws,for clearness of illustration, are shown much less in number thanactually used. The table 13 is provided with As shown, said chains alsopass about guide shafts ing arms 46 as by means of a rod 47 to the framepart i wheels 33 o erating upon a shaft 34 at the front end the machine.

Said chains are coupled one with the other by means of cleats 35 havingtheir leading faces disposed at distances apart equal to the effective,or chain-pitch, circumferences of the sprocket wheels 31 by which thechains are driven.

As illustrated, the shaft 18, which carries the cams 19 and the feedchain driving wheels 32, is rotated from a shaft 36 by means of anendless chain 37 passing about sprocket wheels 18 and 36 on therespective the shaft 36 is driven b means of spur gears 39 and 40 from asha t 41 which, in turn, is driven from the arbor 24 as by means of abelt 42 passing about pulleys 43 and 44 upon the shaft 36 and arbor,respectively. 45 represents a presser roller having its axle journaledin vertically swingwhich are pivotally connected The free ends of saidarms are urged downwardly b means of springs 48 to cause the presser roler to hold against the table a shingle, such. as S, which "is, passingthrough the cutting region oftlie saws.

-49 represents a rotary brush, shown as mounted upon a shaft 5( which isjournaled in boxes 51 depending from the table 13 and extending throughan opening 52 provided in the latter to the rearof the opening 29.

As shown, the brush is driven from the, saw arbor by an endless belt or.chain 53 passing about wheels 54 and 55 upon the arbor and shaft 50,respectively.

said cams act in The function of said brush is to remove saw dust, andloose fibrous material from the underside of the shakes and, to ensuretheir being acted upon by the brush when traveling over the same, Iprovide above the brush a presser roller 56. i

This roller has its axlejournaledin arms 57 which are pivotall connectedby means of a rod 58 to the rame part :12 and is urged downwardly uponthe work by means of springs 59. L e

In each rotation of the cams, thetableis alternately elevated therebyand returned by gravitation into a position (in which the saws arecapable of operating upon-shin les,

timed relation or sync ronously with the feed chains 30 in a manner thata shingle will be operated upon by the saws to produce a shake of 'thecharacter shownin Fig. 5.

More particularly, the shingle, as represented by in Fig. 1, upon. thetable 13 and thereupon is conveyed point end in front by. a feed-chaincleat 35 in the direction indicated by arrows an under the presserrollers 45 and 56 successively.

As the leading, or point, end of the shingle (gierator places a travelsover the saws the latter are ineffective because, at that time, thetable is elevated by the action of the cams.

In the further progress of the shingle,

While I have illustrated and des cribed the preferred embodiment of theinvention, I do not wish to be understood as confining myself theretoexcept aslimited by the scope of the appended claims.
